My DD reads lots of psychological books and she once gave me a good advice: if you want to achieve something, visualize it first. At that time I was about to leave my workplace but I wasn't sure whether I really had to do it so I postponed it again and again. After discussing it with her, I did a photo collage with pictured of lady who looked like me in some ways sitting in the good office and being very busy with her work, I added a picture of money and a picture of friendly colleagues, etc. Then I looked at it every day and that's how I got the courage to leave my previous job and look for another one. Funny enough, I had a very good office and my colleagues were very nice and friendly! And the salary also was good, so yes, maybe these psychological things do work.
